1 PHONOGRAPH DISK OR RECORD.

Application filed .Tune 26, 1919. Serial No. 306,861.

To all whom it may cancer/n:

Be it known that I, JOHN P. WRIGHT, a citizen of the United States, residing at N ewark, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Phonograph Disks or Records, of which the following is a specification.

My invention relates to an improvement in phonograph disks or records.

The object of the present invention is to provide a disk or record of reduced weight and increased strength, as compared with records now in use. In this present invention it is possible to provide a thinner as well as lighter, and yet stronger, record than has hitherto been obtained.

With these objects-in view this invention is characterized b an impressionable compound or c0mpos1tion,-such as bakelite or any other phenolic condensation product or anything, in laminations held together by a binder of the above material, or the like, even glued together with ordinary glue, or other products having characteristics that will permit of an impression being taken or made therein; all of which may beprovided with a reinforce, either at the back or imbedded therein of some woven material, such as'metal.

In the accompanying drawings Figure 1 is a plan view of a disk or record, and igs. 2 and 3 are sectional views through the same.

A is the disk or record, which is made up of bakelite or any other phenolic condensation product, or in fact anything having the 7 same general characteristics, such as ordinary glue for instance, that will take or receive an impression and this may be in .a solid 40 homogeneous mass, or made up of separately treated laminations of fabric, saturated or surrounded and imbedded in the composi tion: and the numeral 1 represents a backing or reinforcing which is preferably on the back but which might be imbedded in the .body of the disk or record, and which is in the form of a layer or layers,

including woven metal.

In other words, this invention contemplates a disk or record of'laminations compressed after being coated or saturated with a binder which might be bakelite or any other phenolic condensation product, or anything having the same general characteristics, as for instance, the laminations might be glued together with ordinary glue with one or more layersof reinforcing fabric of woven metal to strengthen and sustain it, thus producing a strong, tough, light, and if necessary, thin impressionable disk or record for phonographs and the like.

I claim:

A disk or similar device made of laminations of material treated with a binder of bakelite or its equivalent and reinforced with woven metal.

In testimony whereof I afiix my signature.

JOHN P. WRIGHT.
